Variable stars in the globular cluster M79    [PDF]

Grzegorz Kopacki, Andrzej Pigulski

We present preliminary results obtained from analysis of the VI photometry of the globular cluster M79. Stellar variability survey performed with the image subtraction method yielded six new pulsating stars: two of RR Lyrae type, three SX Phoenicis stars and even one W Virginis star. Using all eleven RR Lyrae stars known in the cluster we find that M79 is Oosterhoff type II globular cluster.
